新型声波降粘防措装置由上、下接头、振动簧片和收缩喷嘴构成。装置安装在抽油泵泵简之下，尾管之上，在压差作用下井下流体以较大速度从装置的喷嘴射出，冲击振动簧片，产生机械振动声波，油水混合液在声波中产生相应的声波力学效应和分散乳化作用等，使混合液在油管内的粘度降低，蜡晶不易聚集长大，从而达到降粘防蜡延长油井热洗周期的目的。室内试验及现场近20口井的应用情况表明，这种装置具有结构简单、成本低廉、应用方便等特点，具有明显的降粘防蜡效果。
New sonic viscosity reducing device by the upper and lower joints, vibration reed and shrink nozzle composition. The device is installed under the pumping pump, and on the tail pipe. Under the action of pressure difference, the downhole fluid will exit from the nozzle of the device at a relatively high speed, impacting the reed to produce mechanical vibration sound waves, and the oil-water mixture will generate corresponding sound waves Sonic mechanical effect and dispersion emulsification, so that the viscosity of the mixture in the tubing to reduce the wax crystal is not easy to gather and grow, so as to achieve the purpose of reducing viscosity and wax extend oil hot wash cycle. Laboratory tests and field application of nearly 20 wells show that the device has the advantages of simple structure, low cost, convenient application and the like, and has obvious effect of reducing viscosity and preventing wax.
